Part Number: LM3445 Hi,I don't find the description of OVP and softstart in LM3445 datasheet.How can I achieve OVP and softstart fuction with extra components?
Part Number: LM3445 Other Parts Discussed in Thread: TPS92314A , LM3447 Hi, my name is Fabrizio and I'm interested in LM3445 as led driver in flyback configuration.
I can't find any calculation tool or excel sheet.
Can you help me?
Part Number: LM3445 I am using the LM3445 in accordance with the application note SNVS570M
At low dim levels the buck converter transitions from regulating the current to constant on state of the switching transistor.
From the application note:…
Part Number: LM3445 Dear all:
I find two OVP circuit for LM3445 here.
My colleague want to find a simpler OVP solution.Is there any other simpler OVP solution?
Thanks!
Part Number: LM3445 Hi team,
My customer would like to design searchlight equipment and they think LM3445 should be possible candidate.
The specification they need are
1. Vin=90Vac~264Vac
2. Vout <40Vdc (LED number is not confirmed)
3. Iled…
Part Number: LM3445 Hi,
We have a High PF flyback triac dimmable project,and we are going to use LM3445.I want to design the driver refer to AN-2034. But the Line regulation is not good.Do you have improve solution? Thank you!
